GENERAL DESCRIPTION

The SGM2580 is a single channel power distribution

switch. The switch operates from a wide range of 2.5V

to 5.5V supply voltage, and is controlled by the EN pin.

It can be used in USB power distribution applications.

A 100mΩ low RON N-MOSFET is integrated. The small

size and quiescent current make the device very suitable

for space limited, battery-powered applications.

A number of protection features are provided in the

device including soft-start, current limit and thermal

shutdown. Thermal shutdown shuts off the output

MOSFET and asserts the nFAULT output if the die

temperature exceeds +150℃, and the output MOSFET

remains off until the die temperature drops to +130℃.

The nFAULT pin asserts low during fault conditions

after a 13ms blanking time to prevent false reporting.

SGM2580 is available in a Green SOT-23-5 package. It

is rated over the -40℃ to +85℃ temperature range.
